A Daring Rescue

Trudge through the slime toward the back of the room, where you discover the power generator seems to be missing many parts. Luckily, there happens to plenty of spare parts within the objects around. Repair the generator and throw the switch to inject power to the machine-operated door. That's only one side; in order to power up the other side, Croc needs to yank off the door to the left. Glide across the water as Penguin and pull the lever here.

Notice the shiny manhole cover on your back to the door. Bomb it open with a penguin bomb and drop down as Croc. You will find a LEGO canister on the very right.

The next room is a fun one. Whatever colored pipe you jump into, you pop out of the same corresponding pipe elsewhere. Slip into the yellow pipe, assemble this half of the zipline and glide across to complete the other half. Take the green pipe and bore a hole into the wall to unveil the red pipe. Take the red pipe to the other side and rip the heavy door off the wall. Simple!

Use the Joker on the purple generator and enter the room. Smash and build things for a LEGO canister. On the top most floor on the left side, a particularly heated area in the corner can be accessed as long as you have the Heat Protection Suit. Push the object into the upper right corner and activate the crank. Take the water jet to a LEGO canister.

All the objects, including the metal bars on the left, in the sewer water below contribute to building a giant crocodile craft. Once it comes to life, hitch a ride on its back and plow through the sewers, causing mayhem among the workers. Destroy five green boxes for a LEGO canister.

At the end of the enjoyable crocodile ride, hop off and head up the left staircase. Shatter the glass door and throw the lever. The once smooth slope surface staggers into a staircase, allowing you to take them up to the LEGO canister in the room above.

Rip off the grate covering the penguin bomb gap and dive into the sewer pipe as Croc. As he is not a strong swimmer, you may need to vigorously tap the jump button and wiggle the control stick around to get Croc to reach the ladder. Once he's out, yank off the other grate cover. Then, send a penguin bomb through to destroy the shiny objects above. The explosion yields a couple of parts for a fan; ride it up to the ladder. In the bathroom (police officers like to all be in there at the same time?), bust the left most toilet to reveal a LEGO canister. An unlikely place, indeed...

The seemingly invincible water cooler in the bathroom easily crumbles before the Sonic Suit. Build the leftover pieces into a projectile launcher. Head past the broken mirrors and lug the heavy box on the left to the right. Grapple up, glide across, and access the green panel. This activates the elevator; glide back across to obtain a red power brick.

The scuff marks on the floor indicate that something has been dragged along this floor before. Kick down the door to your right and drag the hefty safe out, following the marks on the floor. Hop atop it and climb over to the fenced-in area. Step on the valve to open the way to the next area.

Deliver 25 LEGO pieces to the Attracto machine for a LEGO canister. Stand at the booth with a mind-controlling character to gain access to the lower level. Here, you need to take three vehicles and park them on their specific pads. Set the van in the left pad. As Mr. Freeze, freeze the water puddle, then ride the bike to the far right. The patrol car belongs in the middle pad. Keep in mind that the van and patrol car need to be built from the surrounding objects. For your efforts, you get a LEGO canister.

In the jail, lift away the right jail door and smash the objects inside to build a fan. Use it to reach the second floor. Activate the lever to free all the prisoners and bomb the shiny door.

A series of magnetic strips along the left wall lead up to this LEGO canister.

Climb the ladder on the right and glide across to hit a switch. Build the dropped pieces into a good old fashioned bomb. To the right of Catwoman's cell is a LEGO canister that you must get before roll the volatile explosive down the stairs to break into Catwoman's holding cell.
